It fits drills, impact drivers, and other compact 18V tools in the Grizzly lineup that share the same slide-in connector and voltage rail. Swap it in directly — no modifications needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGrizzly 80001146, 80001147, 2020, 2040 compatibility:\u003c\/strong\u003e\n    These four models run the same 18V rail and use an identical connector footprint with matching BMS handshake logic, which is why one cell pack covers all four without adapter hardware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through motor-start inrush loads on a drill platform and confirmed the BMS handles trigger-pull current spikes without tripping into protection mode under normal use conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load conditioning:\u003c\/strong\u003e\n    Run the tool at half load for two cycles before full-torque applications — this lets the BMS profile the motor's inrush current draw and calibrate its overcurrent threshold before you push maximum demand.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush surge with Grizzly drills\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger hard on a Grizzly drill, the motor draws a short inrush spike — often three to five times the running current. A BMS that hasn't profiled that motor yet can read the spike as a fault and cut the cell output instantly. This is not a defective battery; it's a protection trip. Run two partial-load cycles first so the BMS logs the inrush pattern and widens the cutoff window accordingly. After that, full-torque trigger pulls should clear without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red and refusing to accept the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that have been stored for several months can drop below the charger's acceptance threshold — typically around 2.5V per cell. When the Grizzly charger sees a pack below that floor, it blinks red and refuses to start a charge cycle rather than risk pushing current into a potentially damaged cell. Leave the pack on the charger for 15–20 minutes anyway; most Grizzly chargers include a trickle pre-charge mode that will nudge cell voltage up to the acceptance threshold before switching to full charge. If the light stays red past 30 minutes, measure pack voltage across the terminals — anything below 10V on an 18V 4-cell pack means the cells need a manual recovery charge at 0.1C before normal charging can resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416046501978,"sku":"BWCS-WRX540PW-1","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416046534746,"sku":"BWCS-WRX540PW-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416046567514,"sku":"BWCS-WRX540PW-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WRX540PW-1.webp?v=1779759709","url":"https:\/\/batteryweb.com\/products\/deltafox-grizzly-80001146-replacement-battery-18v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
